Retail Media Is Growing. Advertiser Confidence Isn't Keeping Pace.
Retail media is your fastest-growing revenue stream, but only if your advertisers (supplier partners) believe in what you're building. Voice of Retail Media gives you the intelligence to earn their trust, prove your value, and unlock greater investment.

Retail Media is Booming. Advertiser Confidence is Not.
Retail media is projected to reach $175 billion globally by 2028, making it one of the fastest-growing investment areas in consumer goods. Retailers everywhere are racing to claim their share. But a significant gap is emerging between the retail media networks being built and the confidence their advertisers actually have in them.

Without a clear view into advertiser sentiment, you're flying blind. You may be losing investment to competitors, or missing opportunities to deepen partnerships, without ever knowing why. The retailers who will win in retail media are those who close this gap first.
Hear What Your Advertisers Really Think of You
Voice of Retail Media is a benchmarking intelligence program that captures the real-time sentiment of your advertisers (supplier partners) about your retail media network. Built on AGI's proprietary research methodology, it gives you the structured feedback and competitive context you need to act (not just react).
Voice of Retail Media answers the questions that matter most to your retail media business:
- How do your advertisers rate the ROI of your retail media offerings?
- Where do you stand against competing retail media networks?
- Which gaps in transparency, data or execution are limiting advertiser investment?
- What would convince your advertisers to invest more?
Short, Frequent Check-Ins. Continuous, Actionable Intelligence.
Voice of Retail Media is designed to fit inside how your business already runs, not add to the overhead. Through brief, structured surveys with your supplier partners, we surface the insights that matter and deliver them in a format your team can act on immediately.
We conduct structured surveys with your advertiser base, collecting feedback on ROI perception, campaign transparency, data quality, and media package accessibility. Surveys are designed to be quick and high-completion.
Your results are benchmarked against our global dataset, including comments from suppliers and retailers across 40+ countries. You see not just where you stand, but how you compare to the best-in-class retail media networks.
We translate the data into prioritized recommendations. You leave each cycle knowing exactly where to invest to increase advertiser confidence, which gaps are most at risk, and what your top advertisers want to see more of.
Build Advertiser Confidence in Your Retail Media Network
AGI offers two supplier listening models to help retailers understand advertiser confidence, benchmark performance, and unlock the investment that drives retail media growth.

Track advertiser sentiment on your retail media network through short, frequent check-ins. Voice of Retail Media captures real-time feedback from your advertiser (supplier) base on ROI, transparency, execution, and data quality, so your team always knows where confidence is strong, where it's slipping, and what to do about it.

Benchmark your retail media performance against a competitive set and an all-industry standard, so you can see where you lead, where you lag, and how you are trending over time. The Retail Media Global Benchmark turns advertiser feedback into actionable priorities your team can execute on. AGI manages the full program end-to-end, from design to execution.
Gain Clear Visibility Into Retail Media Performance
Voice of Retail Media measures advertiser satisfaction and investment decisions across four key pillars: Partnership, Execution, Impact, and Investment. Each pillar maps to specific, competency-based measures, giving retailers precise, actionable feedback rather than broad impressions.
Make Retail Media a Measurable Growth Driver
Retail media growth depends on advertiser confidence. When suppliers question returns, execution, or performance visibility, investment slows. AGI's Voice of Retail Media gives retailers an honest, advertiser’s perspective, and the insights to unlock incremental investment.
Get a clear, unbiased view of how advertisers experience your retail media offer, covering partnership, execution, impact, and investment (not just internal signals).
Know exactly which capabilities and service improvements will have the greatest impact on advertiser spend, so you can prioritise effort and resources more effectively.
Conducting an independent benchmark signals to advertisers that you take their experience seriously, building trust and reinforcing your position as a credible retail media partner they rely on.

Frequently Asked Questions
Common questions from retailers considering our Voice of Retail Media supplier listening program:
The survey is designed to cover the full scope of a retailer's retail media offer. Respondents rate each retailer's platform based on their own experience with it — so whether a retail media proposition is broad or more focused, the survey adapts naturally to reflect that reality.
Voice of Supplier programs typically include one question on the overall effectiveness of retail media. The Retail Media Global Benchmark goes significantly further — evaluating four specific pillars of performance: Partnership, Execution, Impact, and Investment. It also uses a broader, more global competitive benchmark set and targets a respondent community of retail media practitioners and decision-makers, rather than general account contacts.
Identifying the right respondents is essential to the quality and relevance of the results. AGI works closely with each retail partner to build and validate the contact list before fieldwork begins, ensuring feedback comes from people with direct experience of the retail media platform being assessed. These respondents are typically distinct from those participating in annual Voice of Supplier programs.
Yes. The program is available to both retailers and their retail media agencies — for example, a retailer's in-house or affiliated media business. Regardless of who commissions the program, AGI ensures the relevant retailer remains informed and aligned throughout the process.
Survey participants are professionals with direct experience of the retail media platform being assessed. Key functions typically include: Brand, Category, Central Insights/CMI, eCommerce, Innovation/NPD, National Accounts, and Shopper Marketing. This respondent profile is intentionally different from those who participate in the annual Advantage Report.
